BEFORE YOU BEGIN
• We recommend using alkaline batteries for the remote sensor and the main unit. If outdoor
temperatures regularly fall below 32°F (0°C), we recommend using lithium batteries.
• Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct
power requirements).
• ALWAYS install batteries in the remote sensor before the main unit.
• Insert batteries before first use, matching the polarity as shown in the battery compartment.
• Press RESET after each battery change with a paper clip or similar tool.
• During an initial setup, place the main unit close to the remote sensor.
• After reception is established (the remote temperature will appear on the main unit’s display),
position the remote sensor and the main unit within the effective transmission range of
160 feet (50 meters).
• The remote sensor can be placed indoors or outdoors, depending on the area where the
temperature is intended to be measured. If you intend measuring outdoor elements, place
remote sensor outdoors
• The main unit must be placed indoors.
NOTE:
1. Avoid pressing any buttons on the main unit before the remote readings are displayed.
2. The effective operating range may be influenced by the surrounding building materials and
how the receiver and transmitter are positioned.
3. Place the remote sensor so that it faces the main unit (receiver), minimizing obstructions
such as doors, walls, and furniture.
4. Though the remote sensors are weather-resistant, they should be placed away from direct
sunlight, rain or snow. The best suggested location for the remote sensor for outdoors is
under the eave on the north side of the building.
NOTE: When the temperature falls below freezing point 32°F (0°C), battery voltage will
drop which may result in reduced the transmission range. For optimum performance in
cold conditions, we recommend using lithium batteries.

PLACEMENT
REMOTE SENSOR
• The remote sensor should be placed under eaves or a similar location with free air circulation,
sheltered from direct sunlight and extreme weather.
• Ideally, place the remote sensor over soil, rather than asphalt, which would cause
false readings.
• Avoid placing the remote sensor near sources of heat, such as chimneys and heating elements.
• Avoid areas that collect heat from the sun and radiate heat, such as metal, brick or concrete
structures, paving, and patios.
• The international standard for the valid air temperature measurements is 4 feet (1.25 meters)
above the ground.
MAIN UNIT
• Make sure that the main unit is locating within the operating range of all remote sensors.
• Ideally the main unit should be placed within line of sight of remote sensors. Avoid placing
the main unit where surfaces emitting and radiating heat (e.g. heating ducts or air conditioners)
and areas with interference from wireless devices (e.g. cordless phones, radio headsets, baby
monitoring devices and other electronics).

GETTING STARTED
After batteries are installed; remote sensor will transmit temperature data at 45 second intervals.
The main unit may take up to two minutes to receive the initial readings. Upon successful
reception, remote temperature will appear on the top line of the main unit’s display (the default
remote channel is channel one). The main unit will automatically update readings at
45-second intervals.
After communication between the main unit and remote sensor has been established,
secure the remote sensor in the desired location.
If no signal is received from the remote sensor within two minutes, dashes [- - -] will be
displayed. Press and hold the DOWN (? ) button on the main unit for two seconds to initiate
another signal search.
REMOTE AND INDOOR TEMPERATURE
The remote temperature information line is located on the top line of the main unit’s display.
The wave icon is located above the remote channel number indicates the reception status from
the corresponding remote sensor.
There are three following types of the reception status may be displayed:
The unit is in a searching mode.
Temperature reading is securely registered.
No signals detected.
The indoor temperature with the icon IN is located below the remote temperature
information line.
NOTE: If the indoor or remote temperature goes above or below operating range stated
in specifications, the main unit’s display ( weather) will show dashes “- - -” on the
corresponding line.
MAXIMUM AND MINIMUM READINGS
The maximum and minimum record of the indoor and remote temperature will be automatically
stored in the memory of the main unit (receiver).
To display the minimum, maximum or the current reading press MEM button.
If no button is pressed for the next 15 seconds, the unit will return to the current temperature
and humidity display.
To clear the memory, press and hold MEM button for two seconds and all previously stored
readings will be erased.
LOST COMMUNICATION
If the main unit display line for the remote sensor reading goes blank, press and hold
DOWN (? ) button for 2 seconds to begin a new signal search. If the signal still isn’t received,
please make sure that:
• The remote sensor is in its proper location.
• The distance between main unit and remote sensor(s) is not over 160 feet (50 meters)
• The path between units is clear of obstacles. Shorten the distance if necessary.
• Fresh batteries are installed correctly in both remote sensor and main unit.
7
If there is no reception, please perform the following steps:
• Bring the main unit and remote sensor close together.
• Remove four (4) small screws from the back of the remote sensor with small Phillips
screwdriver, and open the battery compartment.
• Remove the batteries from the battery compartment and reinstall them in the same manner.
Remote sensor LED indicator will flash showing transmission of the signal.
• Remove the batteries from the main unit and reinstall them in the same manner.
• On the main unit select the same channel number using CHANNEL button as set on the
remote sensor. The remote temperature appeared on the main unit’s display will show that
transmission is being received successfully.
TRANSMISSION COLLISION
Signals from the other household devices such as wireless doorbells, home security systems,
and entry control, may interfere with this product or cause temporary reception interruption.
This is normal and will not affect the general performance of the product. The transmission and
reception of the temperature and humidity readings will resume once the interference subsides.
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology) radio station (WWVB) is located
in Ft. Collins, Colorado. It transmits an exact time signal continuously throughout the most of
the continental United States at 60 KHz frequency. The unit can receive this WWVB signal
through the internal antenna from up to 2,000 miles away. Due to the nature of the Earth’s
ionosphere, reception can be limited during the daylight hours. The radio controlled clock will
search for an alternate station that receives the atomic time signal from the NIST Atomic clock
in Boulder, Colorado.
The WWVB tower icon on the unit’s display will flash indicating a radio signal reception from
the WWVB station. If the tower icon is not fully lit, or if the time and date are not set
automatically, please consider the following:
• During night-time hours, atmospheric disturbances are typically less severe and radio signal
reception may improve. A single daily reception is sufficient enough to keep the clock
accuracy within 1 second.
• Make sure the unit is positioned at 8 feet (2 meters) distance from any interference source
such as a TV, computer monitor, microwave, etc.
• Within concrete wall rooms such as basements or office buildings, the received signal may be
weakened. Always place the unit near the window for better reception.
ATOMIC CLOCK
Immediately after establishing communication between the main unit and remote sensor, the
atomic time signal receiver will open and start to search for the atomic time signal. The search
usually takes between 5-8 minutes.
NOTE: Do not press any buttons on the main unit during auto search as it may interrupt
product’s operation, and you will need to start set up procedure again.
Once the atomic time signal is received, the date and time will be set automatically, and the
[ ] icon will appear.
NOTE: It is necessary to set your Time Zone, having in mind that the default zone is a US
Pacific Standard Time (PST). (Refer to MANUAL SETTINGS section)
If the time signal has not been received in 8 minutes, you may use the MODE button to set the
time and date manually. (Refer to the MANUAL SETTINGS section).
After the clock is set manually, place the Weather Station by the window for the better
reception. The atomic clock receiver is programmed that it will continue to search for the
atomic time signal daily for every hour between 1:00 am and 4:30 am.
Once the time signal has been successfully received, the time and date will be
updated automatically.
